Re: [GUSDEV] new Undo plugin

[Chris T. <cmt...@gm...>]

what about storing which row/tables were updated by an
algorithm_invocation_ids? I'm new to GUS. Is this done already? Am I correc=
t
in assuming that algorithm_invocation_ids are created every time a
particular plugin (algorithm) is run or are there multiple
algorithm_invocation_ids per plugin run?

Is there a way of enforcing plugin version tracking? I guess what I'm askin=
g
is, is there a way to detect if a plugin has been modified since its last
use?
